Microcomputer dual-way timer switch internal battery function

Microcomputer dual-circuit timing switch is a new type of astronomical time automatic control device for lighting equipment developed and produced by Baowa Company.

Embedded with professional astronomical software, it can accurately calculate the sunrise and sunset time data for every day of the year in a certain place. Automatically control outdoor lighting on and off through complex procedures such as precise perpetual calendar clock and correction calculations. (Recommended learning: webfront-end video tutorial)

Overcomes the shortcomings of microcomputer timing switches that are generally controlled according to standard time and require frequent manual correction.

2. Functional features

1. LCD displays year, month, day, hour and minute, with backlight for nighttime observation and operation, Chinese interface.

2. Complete functions: equipped with manual mode, time control mode, astronomical clock mode, special day mode and other functions.

3. The latitude and longitude astronomical clock is a programmed astronomical clock with a built-in micro intelligent controller. It can automatically calculate and adjust the astronomical control time with high precision according to the local dawn and dark times.

4. According to the changes in the four seasons of the year, use the longitude and latitude algorithm to calculate the switching time, and control it reasonably with seasonal changes. There is no need for regular manual adjustment, and the switching time is fine-tuned in steps of 1 minute.​

5. It has the function of selecting the number of channels, which can be easily set to control 1-6 channels, and each output loop can be controlled independently.​

6. It has week mode control. For example, the light switch time can be personalized from Monday to Sunday.​

7. It has power-off data storage, the clock works continuously, there is no need to replace the battery, and the clock can be kept running for more than ten years.

8. It has strong anti-interference ability and can withstand interference pulses with an amplitude of up to 2000 volts directly input from the power grid.​​​

9. High-power relay output, can be connected to 220V or 380V contactor, stable control, long service life.

10. It can effectively improve the lighting control quality and reduce the maintenance workload.

3. Product application scope

can be widely used in municipal roads, railways, stations, freight yards, lighthouses, ports, mines, factories, navigation beacons, lighting advertising and Automatic control of all outdoor lighting in military barracks and other areas.
